I had just begun viewing the stars that night sitting S. of our house on our rural 5 acres away from the house lights. Facing south I surveyed the sky looking up & around at various areas of the sky. Bringing my head back around to the S. facing direction, I was surprised to see a darker space ahead of me about 200 ft. high & less than 3 miles away. I determined it was a solid object by the fact it was blocking out the few stars I had seen in that direction. It appeared to be a triangle shape that was wider that the height of it's apex. There were no lights - the sharpest edges were hard to focus on, they seemed to have a black smoke swirling around them. After just a few minutes it moved away farther to S. in instantly shifting positions.
